The 17-year-old son of an Omaha police detective opened fire at his high school yesterday, shooting the principal and assistant principal, who later died of her injuries. The principal is in serious but stable condition, AP reports. The student, identified as Robert Butler Jr., fled the school and fatally shot himself in his car.

Butler—who had transferred to the high school in October—did not shoot any students. In a rambling Facebook post, he blamed Omaha and the high school for changing him, and said he wanted people to remember the person he was before. "He was popular with students and seemed real pleasant," the principal of his previous high school told the Omaha World-Herald, describing Butler as "a fairly normal, average" student.
